How much total interest will I pay on this $20K loan?

The total interest paid will be approximately $25.6K (128.0% of principal). For smaller balances, even a slightly higher interest rate doesn't add massive sums to the total cost, but paying it off quickly is still optimal.

Is borrowing $20K a good idea?

For minor expenses, borrowing $20K is only recommended if it resolves an emergency or high-priority need. If the $127 payment exceeds 10% of your take-home pay, consider pulling from savings instead.

Should I extend the term from 30 to 35 years to lower the payment?

While extending to 35 years drops the monthly burden, it significantly boosts your overall interest ($25.6K). For small loans, keep the term as short as you can comfortably afford.

Are there benefits to paying off this $20K loan early?

Absolutely. Paying extra principal each month reduces your $25.6K interest burden. Most small personal loans do not have prepayment penalties, but verify with your specific lender.
